THE COMPOSITION OF ATMOSPHERIC DEPOSITION AND SOIL WATER IN THE MIXED FOREST OF THE PRIOKSKO-TERRACE STATE NATURE RESERVE

Abstract

The paper presents the results of water sample collections during the spring-summer period of 2024 at the forest and open areas of the Prioksko-Terrasny State Nature Reserve. Significant variation in the main indicators of atmospheric deposition and soil water was observed. The export of dissolved organic carbon with soil water during the spring-summer period exceeded the input from atmospheric deposition. The carbon export from the upper 0-10 cm soil layer during the spring-summer period at the forest site was 0.3% of the reserves, while at the open (meadow) site it was 0.6%. The carbon export from the upper 0 -20 cm soil layer during the spring-summer period at the forest site was 0.1% of the reserves, and at the open (meadow) site it was 0.2%. The results highlight the importance of monitoring atmospheric deposition and soil water for assessing the carbon balance in forest ecosystems.
